VALVE.

' The invention consists essentially of the novel constructionandarrangement of parts, whereby the seat maybe readily removed andreground.

The objects of the invention are to avoid the expense incident to theremoval of the complete casing for repairs to the seat, to facilitatethe operation of steam and water installations for heating and all otherpurposes by avoiding leaky valves; to effect repairs and replacement ata minimum expense and in a short period of time; and generally toprovide an eflicient, durable and serviceable valve.

In the drawings, Figure 1 is a side elevation of a faucet broken away todisclose the inside of the casing, and the valve and seat.

Fig. 2 is an enlarged perspective detail of the valve seat. Fig. 8 is anenlarged perspective view of the washer under the seat.

Fig. 4 is an enlarged perspective view of the locking screw for theseat. 7

Fig. 5 is an enlarged perspective view of the washer.

Fig. 6 is an enlarged perspective detail of the nut for the lockingscrew.

Like numerals of reference'indicate corresponding parts in the figuresillustrating two forms of the invention respectively.

Referring to'the'drawings,in Fig. l a

faucet is illustrated in which 1 is the valve casing, 2 the spout, and 3the connection to the water feed pipe.

The partition 4: within the casing 1' represents the customary divisionbetween the feed and the spoutand is formed with the usual dischargeorifice 5 at the edge of which the annular flange 6 projects upwardly asusual forming what I term a bottom seat, thls flange being topped by thewasher'7,

which in common practice would form the seat below the valve 8 operatedby the ham dle 9 at the end of the stem 10.

The removable or upper seat 11 is mounted I on the washer 7 and issuitably ground to meet the valve 8. The seat 11 extends in V the formof a ledge over said washer 7 from the body 12, from which projects theV-bar 13 having a locking bolt hole 14 at the juncture of the legs.

' The locking bolt 15having the under bev- Y 1 eled head 16 crossslotted at 17 for a driver is inserted through the hole 14' and isthread-. ed vfor the greater portion of its length, the

threaded end 18 projecting through the'casing 1 at the lower end andthrough the washer 19 into the nut 20, which looks the seat firmly inplace and at the same timemoved by means of a screw driver and the seatlifted out and subsequently replaced or I reinstalled.

It must be understood, that variations, in the design and constructionalfeatures may occur without departing from the spirit of the inventionand that the novel elements are pointed out'in the claimffollowing.
